Hi Tim,

 

I’d be happy to take a look at this for you.  Is the code somewhere I can access?  If not please send the database file, protocol file, and complete output when you start the IOC with asynTraceIODriver enabled on the serial port.

Hi,

 

I am developing an EPICS asyn stream device for a Hirst Magnetics GM08 handheld unit and probe.

 

I think I have tied down my development and my MVP is going to be just reading a stream that is polling every second, without me sending an RS232 command down the line.  It is a fairly simple device communicating at 9600,N,8,1 and I can use screen /dev/ttyS0 9600 in Ubuntu 20.00 to have the device send back terminated data.

 

Looks a bit like this where the left float is a milliTesla and the 300 is stated units.

00.020 300CrLf

00.002 300CrLf

-0.001 300CrLf

 

When I try to hook this up to stream and asyn using the latest devices against drvSerial and with the debug loaded.  I’m having a hard time getting the INP to read the data

 

I have turned on asynTraceMask and get no chatter, plus used the stream debug to see it connect on /dev/ttyS0 at the permissionable addressed Linux COM1 on my motherboard. I get something with not being able to instantiate the PV when I do a dbtr HIRST1:current_value.

 

Has anyone developed EPICS against this?  Or would a kind person take a glance at my IOC development?

 

Kind Regards
